For some of you this must seem a strange title for a thread but for those of you with a Nanocom hopefully it will not.
Anyway the truck felt a bit lumpy the other day, it's a 4.0 litre Thor engine running on LPG, so I plugged in the Nanocom and although it shows no faults, when I had a look at inputs and roughness settings cylinder 7 was showing a value sometimes as high as 3.0 whilst all other cylinders were 0.00. Any ideas anybody?
 
a petrol engine doesnt successfully fire every cylinder 100% of the time. its completely normal and displayed in nanocom as roughness. i dont recall the figure but there is a predetermined count before a number of misfires are registered as an actual misfire
an occasional blip to 3 shouldnt be much of an issue, but if its consistent, then it needs to be checked out, possibly a bad plug or lead

Thanks Kermit, that was a quick respnse. I'll change the plug and let you know.
